Description

Die Erfindung betrifft- ein- Brennstoffventil fürThe invention relates to a fuel valve for

Kraftfahrzeuge. - - . - -Motor vehicles. - -. - -

Bei Kraftfahrzeugen, insbesondere bei Motorrädern, wird der Brennstoffbehälter, mit beständigem Niveau vorzugsweise am Rahmen befestigt, --.um zu. verhindern, daß die Motorschwingungen das dichte Schließen des Nadelventils des Behälters nachteilig beeinflussen. Der Behälter muß dabei in der Nähe des Vergasers angebracht werden, um ίο Störungen im Vergaser infolge unregelmäßigen Abfließens des Brennstoffes zu vermeiden.In motor vehicles, especially motorcycles, the fuel tank is made with a durable Level preferably attached to the frame, -. To. prevent engine vibrations adversely affect the tight closing of the needle valve of the container. The container must be in near the carburetor to avoid ίο malfunctions in the carburetor as a result of irregular Avoid draining the fuel.

Es ist ein bekannter Übelstand, daß durch plötzliche Geschwindigkeitsänderungen beim Anfahren oder Bremsen der Brennstoff, der sich in der Leitung zwischen dem Speiseibehälter für den Vergaser und dem Vergaser selbst befindet, sich infolge seiner Trägheit häufig so bewegt, daß er entweder in den Behälter zurückfließt oder "plötzlich in den Vergaser strömt, wodurch Unregelmaß igkeiten im Lauf des Motors eintreten.- ·-· -It is a well-known drawback that there are sudden changes in speed when starting up or braking the fuel that is in the line between the food container for the Carburetor and the carburetor itself is, due to its inertia, often moves so that it either flows back into the container or "suddenly flows into the carburetor, causing irregularities in the running of the engine.

Die Erfindung sieht ein Ventil vor, das in die genannte Verbindungsleitung eingesetzt wird und solche plötzlichen Brennstoffbewegungen in dieser Leitung in beiden Strömungsrichtungen verhindert. Die Zeichnung stellt ein Ventil nach der Erfindung schematisch und beispielsweise dar, und zwar zeigtThe invention provides a valve which is inserted into said connecting line and such sudden movements of fuel in this one Prevents conduction in both directions of flow. The drawing shows a valve according to the invention schematically and by way of example, namely shows

Abb. 3 ist ein Querschnitt nach ~Linie.A-A der Abb. 2;Fig. 3 is a cross-section along ~ line.AA of Fig. 2;

Abb. 4 ist ein Längsschnitt ähnlich Abb. 2, der die Ventilstellung beim Bremsen zeigt.Fig. 4 is a longitudinal section similar to Fig. 2 showing the valve position during braking.

Der Behälter ι enthält den Brennstoff, der den Vergaser 2 speist. Zwischen beiden ist das Ventil 3 nach der Erfindung vorgesehen,-Wie aus den Abb. 2 bis 4 ersichtlich, besteht das Ventil 3 vorzugsweise aus einem scheibenartigen flachen Teil 4, dessen Schaft 5 sternartigen Querschnitt hat (Abb. 3). Das Ventil ist in einer Kammer 6 verschiebbar, die im Durchmesser dem Ventilschaft 5 angepaßt ist und mit dem im Ventilkorper vorgesehenen Kanal 7 in Verbindung steht. Der Kanal 7 befindet sich . in der Verlängerung de'r kurzen Leitung 9, die aus dem Speisebehälter 1 herausführt. Auf der anderen Seite steht die Kammer 6 des Ventils mit der Verbindungsleitung 10 in Verbindung, die zum Vergaser -2 führt. In der Kammer 6 sind zwei Ventilsitze für das Ventil 4 vorgesehen. In gewöhnlicher ArbeitsStellung wird das Ventil 4 vom Brennstoffzufluß in •der Weise verschoben, daß es eine mittlere Stellung zwischen den beiden Ventilsitzen annimmt und -beibehält, wie in Abb. 2 dargestellt, so daß, da der j innere Durchmesser der Kammer 6 beträchtlich größer als der äußere Durchmesser der Ventilscheibe 4 ist, der Brennstoff frei in die Leitung 10 fließen kann, wobei es den Umfangsrand des Ventils 4 benetzt.The container ι contains the fuel that feeds the carburetor 2. The valve 3 according to the invention is provided between the two, as can be seen from FIGS. 2 to 4, the valve 3 preferably consists of a disk-like flat part 4, the shaft 5 of which has a star-like cross-section (FIG. 3). The valve is displaceable in a chamber 6, which is adapted in diameter to the valve stem 5 and is connected to the channel 7 provided in the valve body. Channel 7 is located. in the extension of the short line 9, which leads out of the feed container 1. On the other hand, the chamber 6 of the valve is connected to the connecting line 10, which leads to the carburetor -2 . Two valve seats for the valve 4 are provided in the chamber 6. In ordinary working position the valve 4 is moved from the Brennstoffzufluß in • the manner that it assumes an intermediate position between the two valve seats and -beibehält, as shown in Fig. 2, so that as the j inner diameter of the chamber 6 is significantly greater than is the outer diameter of the valve disk 4, the fuel can flow freely into the line 10, wetting the peripheral edge of the valve 4.

'Wenn das Fahrzeug gebremst wird, verschiebt sich die Ventilscheibe 4 zufolge ihrer Trägheit in Richtung auf den dem Speisebehälter 1 zugewandten Ventilsitz, so daß es die Verbindung zwischen der Leitung io und der Leitung 9 schließt und verhindert, daß Brennstoff vom Vergaser über die Leitung ίο in den Behälter α zurückfließt (Abb. 4). Bei Beschleunigung des Fahrzeuges ist die Bewegung der Ventilscheibe 4 eine umgekehrte, d. h. sie legt sich zufolge ihrer Trägheit gegen den dem Vergaser zugekehrten Ventilsitz, so daß auch in diesem Falle die Verbindung zwischen den Leitungen 9 und. 10 unterbrochen und verhindert wird, daß durch Trägheit ein Überschuß an Brennstoff aus dem Speisebehälter 11 dem Vergaser ß- zufließt. 'When the vehicle is braked, the valve disc 4 moves due to its inertia in Direction of the feed container 1 facing valve seat, so that there is the connection between the Line io and line 9 closes and prevents that fuel flows back from the carburetor via the line ίο into the container α (Fig. 4). When the vehicle accelerates, the movement of the valve disc 4 is reversed, i.e. H. she because of their inertia lies against the valve seat facing the carburetor, so that in in this case the connection between lines 9 and. 10 interrupted and prevented becomes that by inertia an excess of fuel ß- flows from the feed container 11 to the carburetor.

Hieraus ist ersichtlich, daß mittels des beschriebenen Ventils, das einfach gebaut ist und sicher arbeitet, Unregelmäßigkeiten im Motorlauf ausgeschlossen sind.From this it can be seen that by means of the valve described, which is of simple construction and safe works, irregularities in the engine run excluded are.
